In this study, a circular cross‐coupled dielectric waveguide (DW) filter was realized based on 90‐degree sectoral resonators. The filter is formed by splicing four 90‐degree sectoral DW resonators (SDWRs). A shallow blind hole (BH) was set at the center of each 90‐degree SDWR to adjust the resonant frequency. The magnetic coupling between the resonators was realized through the rectangular wall and...
